According to the daily task of the test, the indoor decoration of laboratory purification contains precious instruments and various chemicals, mainly including inflammable and corrosive drugs. In addition, the steam body or steam that may cause harm in actual operation. Therefore, there are unique regulations on the building structure, natural environment and indoor equipment of chemical laboratory purification, which should be taken into account when preparing for new chemical laboratory purification or transforming the original chemical laboratory purification.
The purification land for chemical laboratory is roughly divided into three categories: Instrument Laboratory purification, chemical composition analysis laboratory purification, auxiliary room (company office, storage room, gas cylinder room, etc.). The purification of chemical laboratory shall be prohibited from the natural environment with dust, smoke, noise and vibration sources. Therefore, the purification of chemical laboratory shall not be located near the main road, heat exchange station, main engine room and assembly workshop (except the purification of chemical laboratory in production workshop). In the chemical composition analysis room, the organic chemical solution and analytical measurement of the test sample are carried out. In the work, some small and medium-sized electrical equipment and various chemicals are often used. If the actual operation is not careful, there are certain risk factors.
For this application, the following should be paid attention to in the design and planning of purification and decoration of chemical analysis laboratory:
1. The engineering construction stipulates that the engineering construction of chemical laboratory purification shall be completed with fire prevention or raw materials that are not easy to ignite, and the fire safety characteristics shall be fully considered for decoration partition and roof. The terrazzo floor can be selected, the windows can be antifouling, and the light in the room is better. The door needs to be opened outwards, and the overall purification planning of the large laboratory needs to set up two entrances and exits to facilitate the evacuation of staff in case of accidents.
2. The power supply of power supply and drainage pipeline shall ensure the necessary pressure, water body and water flow to consider the necessity of all normal operation of the experimental instrument. The main gate valve in the room shall be built in an obvious position easy to operate. The sewer pipe shall be made of corrosion-resistant raw materials, and the road surface shall be provided with odor proof floor drain.
3. The natural ventilation equipment often causes harmful or flammable vapor in the inspection work, so the purification of chemical laboratory should have excellent natural ventilation standard.
